Tra-Bond 2115 is an optically clear, low-viscosity material suggested for use in the fabrication of lasers. Its low shrinkage during cure reportedly makes this product suitable for laser and optical component applications where proper alignment is critical. It also has been shown to withstand 30 seconds of 60 W direct laser energy and has also been cycled to 4 K in cryogenic applications. This two-part epoxy system is said to be easily mixed and cured at room temperature; heat can be applied to reduce cure time.
